Busy Beaver is not the most visually stunning, original, mind-blowing puzzle game out there. Actually, it feels like what happens when a developer plays around with the idea of creating a Tetris clone, only to accidentally stumble across a little tweak that is just functional to turn into a game. In this case, though, it works.

In Busy Beaver, puzzle pieces fall from the sky, as usual, but players don't control them.
